The Braves announced Medlen’s Tommy John surgery after he was examined Monday by Dr. James Andrews in Gulf Breeze, Fla. This marks the second time in Medlen’s career he has undergone the surgery, with the first being in 2010.

Beachy, who also underwent Tommy John surgery in 2012, was examined by Andrews as well and will travel to Los Angeles to get another opinion from Dr. Neal ElAttrache, the team physician for the Los Angeles Dodgers.

Medlen and Beachy were expected to be a big part of Atlanta’s pitching rotation this season. After they went down, the Braves signed free agent Ervin Santana to a $14.1 million, one-year contract.
